It is with great pride that we announce (AGAIN!) the celebration of our 40-year anniversary!  We thought it appropriate to have a repost of this event, as we have combined the 40^th anniversary with a new cover design of our catalog.  Combine the new catalog cover with our inability to properly celebrate at Pittcon 2022 and you have a recipe for a repost!

As part of our efforts to honor this milestone achievement, we created an interactive timeline of our history.  It can be found at the following link: https://www.pickeringlabs.com/contact-us/about-us/#40-year-anniversary

Our late friend and founder, Dr. Michael Pickering, began this journey in 1982.  As the namesake of our company, Michael’s many achievements are reflected throughout our timeline but also in our company’s logo and especially in our “Guaranteed Chemistry” watermark, which we’ve updated for this special anniversary.  We continue to uphold his legacy of high quality and dedicated support for our customers. 

As you visit the timeline, you’ll be able to relive the important milestones that we’ve reached during the last four decades, including: a United States patent for our Ninhydrin reagent Trione, introduction of our PCX post-column instrumentation, publishment in official methods and many more highlights.  If you look closely at our shiny new 40^th anniversary logo, you may even see a familiar chromatogram or two!

We would like to extend a special “Thank You!” to all of the customers and dealers who have joined us throughout these historic four decades.  We would not be a successful company still today without the trust, partnership and loyalty which you have shown us.  As a small business, we want each of our customers to know that their orders over the years have supported and directly impacted our scientific contributions to the analytical community.  We look forward to our partnership together for many years to come, as well.

And finally, we wish to acknowledge that we could not have made this company a success without our most valuable assets: our employees!  As you may have noticed in the last couple newsletters, our very dedicated colleagues have been celebrating a lot of 20^th and 30^th work anniversaries lately!  This fantastic team works so hard every day to support our customers; we are so proud and grateful to have them. 

Please, we would be honored if you’d pop the champagne, raise a glass, and celebrate with us! 

Cheers to our Pickering Labs family!  Cheers to our customers and distributors!  Cheers as well to sustaining Michael’s legacy for another 40 years! 

And a clink of our glasses for the scientific work we all do in the world.

For regular readers of the Pickering newsletter, perhaps my longtime partner Paul doesn’t feel like a complete stranger…  After all, one of the perks (?) of being in a relationship with me is that periodically Paul’s name and picture make it into one of my articles, as I often share stories about our life here in the blog.  And at this point, Paul has attended a decade’s worth of Pickering company events!  He was our volunteer Pickering photographer for the Onyx PCX launch party, among other support roles.  Over the last decade, as Paul has become part of my family, he has also become part of the Pickering Labs family.

Paul and I are so appreciative that many members of this great Pickering Labs family were able to be present for our wedding.  It would not have been the same celebration without them!  And certainly, many folks here had been long awaiting the chance to attend this event.  Saji and Anita, for example, have often politely (?) inquired as to when the party would finally occur, since Paul and I were engaged for quite a long time.  After several years of COVID interfering with company holiday parties, it was especially fun to get fancy with the team and spend time with their partners, family and friends. 

Over the years, the PLI team has been such a big part of my life and journey together with Paul… Dating all the way back to the beginning, even!  Paul and I were married in October 2022 on our ten-year anniversary, so one of the earliest ‘boyfriend hurdles’ he actually overcame was gaining approval at his first Pickering holiday party!  I’ll forever cherish my memories of Michael Pickering’s delight upon first meeting Paul, at that very same party in December 2012.  They instantly bonded over their relative statures (I’m quite tall).  Michael pulled me aside to tell me how thrilled he was that I was finally dating a shorter man.  He predicted that Paul would be, as my grandmother says, “a keeper,” and that he would make me very happy.  As it so happens, Michael was right. 

One of the nice things about taking our sweet time to tie the knot was my apparent complete lack of nerves.  I was all smiles getting ready that morning, as you can see!  Not a worry on my face! 

Thanks to the marvelous assistance of our wedding planner and enthusiastic participation of our guests, I’d say the ceremony went off without a hitch, too!

Right after our ceremony seemed like the perfect time for group pictures, although I do hope that the Pickering team didn’t miss too much of cocktail hour.  Farmstead did a fantastic job with the passed appetizers, so hopefully Jim and the team here got enough to eat!

Pickering Labs and our employees are such a huge part of my life.  I am so grateful to have these wonderful people around me, and I don’t just mean only on this celebratory occasion.  They lift me up, and as we support each other, it provides true purpose for my work.  Being part of this team gives me passion for what I do every single day.  The vision Michael Pickering had for this special workplace is a legacy which inspires all of us to put our best efforts towards our products and customers, so that they can impact the world with their essential work.  But these individuals also inspire me, with their warmth and dedication, as well as their commitment and integrity.  When they say “Welcome to the Pickering Labs family,” what they mean is “we will show up at your wedding two hours away, on time and ready to cheer for you, your spouse, and all of your ridiculous music choices!” 

Pickering team, I love you all dearly.  Oh yeah, and I love Paul too, so thank you for your support of our relationship and celebration of our eventual wedding.  Cheers!

Our employee family is growing once again!  Pickering Laboratories is happy to introduce the newest member of our team: Luca Nardin

Luca joined us in August 2022, stepping into his new role as a Production Chemist, with a particular focus on our Reagent manufacturing.  As many of you know, these particular solutions that we sell are always in high-demand, so Luca has been quite busy at the start of his Pickering Labs career!

Outside of work, Luca enjoys hiking, tennis and driving cars.  Like many of his fellow Pickering employees, Luca also has a love of reading.  The particular genre being Fiction and Science Fiction novels.  Luca and his family are from the Venice region of Italy and, maybe owing to this rich historical upbringing, he loves to learn about the medieval and renaissance eras.

Luca is a local product, attending Los Altos High School only 4 miles away from Pickering’s Headquarters in Mountain View.  After high school, Luca matriculated at University of Illinois in Urbana-Champaign.  As you can see from his photo, Luca is still a big Fighting Illini fan!

Welcome, Luca!

Formaldehyde is used in beauty products as a preservative, in the textile industry, in making plywood, composite wood items, adhesives, and many other products. Consumers can be exposed to the chemical in tobacco smoke, construction materials, furniture, carpets, and other household products. Formaldehyde is carcinogenic to humans, causes respiratory problems and skin irritation. It is now in the 20 high priority chemicals list for review by the EPA. In some industries, formaldehyde releasers are used and these slow-release free formaldehyde over time. The free and hydrolyzed forms of formaldehyde can be determined by HPLC method with post-column derivatization.

The Pickering Nash reagent comes in two parts, and can be mixed right before use. We sell two formulations, one according to the AATCC method 206 for colorimetric determination and the other according to ASTM D5910 for free and hydrolyzed formaldehyde for HPLC post-column method.

After recent research into packaging enhancements, we are now offering a replacement for part # NA220 (Sodium Diluent, pH 2.20, 4 x 250 mL). Effective immediately, we will be discontinuing NA220 and replacing with part # NA220L (Sodium Diluent, pH 2.20, 950 mL). The replacement part number, NA220L, will have the same list price as NA220 and is identical in composition.

Please contact Pickering Laboratories Support at (650)694-6700, (800)654-3330, or support@pickeringlabs.com if you have any questions.

As we listen to feedback and engage more with our customers, variations of our current PTS product offering are constantly springing to life!  We have introduced a new Simulated Lung Fluid solution with DPPC Surfactant.   Dipalmitoylphosphatidylcholine (DPPC) is a phospholipid and one of the main pulmonary surfactants found in lung fluid. The main function of DPPC is to reduce the surface tension of liquid in the lungs and to help adsorption of oxygen into the air-liquid interface. It is known to be a difficult process to bring DPPC into solution. With that in mind, we offer a synthetic lung fluid with DPPC dissolved and pre-mixed for your convenience:
